A homework problem - Math Central

Quandaries & Queries

Question from Shawn, a parent:

I'm checking my son's homework and we disagree on the solution.
The problem reads:
135mn^4 (n to the 4th power) over 50n^2 (n squared)

I think the answer is: 27mn^2 (squared) over 10

Can you help?

Shawn,

I agree with your answer. It could also be written 2.7 mn².
